Comment (by afragen):

 Tested [https://github.com/WordPress/wordpress-develop/pull/1492 PR
 #1492].

 I was unable to test the server memory conditions.

 If both the `wp-content/upgrade/temp-backup/plugins` and `wp-
 content/upgrade/temp-backup/themes` are both un-writeable, only the
 plugins folder is noted to be un-writeable in Site Health.

 If either is un-writeable the correct notice is displayed.

 If `wp-content/upgrade/temp-backups` is un-writeable there is no notice in
 Site Health.

 Updating and restoring a failed backup works great!
